Specification of Letters Patent.

Patented Dec. 22, 1908.

Application filed April 19, 1906. Serial No. 312,562.

To all whom it may concern.'

Beit known that I, PATRICK F. CAVA- NAUGH, a citizen of the UnitedStates, and a resident of La Crosse, in the county of La Crosse andState of l/Visconsin, have'invented a new and Improved Faucet, of whichthe following is a full, clear, and exact description.

This invention relates to faucets used for plumbing or other purposes,and is es ecially useful in connection with faucets whic automaticallyshut off the flow of liquid when released.

The object of the invention is to provide a device of this characterwhich is simple and durable in construction, which will not permit theleakage of water when it is not in use, and which is closed by thepressure of the water.

A further object of the invention is to provide an automatically closingfaucet in which no use is made of springs to effect the closing.

The invention consists in the construction and combination of parts tobe more fully described hereinafter and definitely set forth in theclaims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of my invention; Fig. 2 is a similar viewshowing the faucet partly in cross section; Fig. 3 is an enlargedvertical section of a portion of the device 5 Fig. 4 is a horizontalsection on the line 4-4 of Fig. 3, and Fig. 5 is a horizontal section onthe line 5 5 of Fig. 3.

Referring more particularly to the parts, I provide a tubular section 1terminating at one end in a threaded extremity and provided with anintegral nut to permit its attachment to piping. Formed integrally withthe tubular section 1 at the extremity remote from the threaded end, isa body or chamber 2 which is threaded at its upper rim to receive acorrespondingly threaded cap 3. The cap 3 is provided with an integralnut 4 to permit its attachment to the chamber 2. The cap 2 is alsoprovided with an inner recess 19, for a purpose to be describedhereinafter. Formed integrally with the chamber 2, in the bottomthereof, is a nozzle 5 which projects downwardly, and from which thewater flows when the faucet is open. This nozzle 5 is internallythreaded to receive a correspondingly threaded tubular body 6, whichprojects into the chamber 2. I provide between the upper rim of thechamber and a shoulder 6 formed on the cap, a flexible diaphragm 7 ofrubber, cloth or heavy duck. Between the diaphragm and the cap is placeda gasket ring 8 of soft metal or other suitable material. It will beunderstood that the diaphragm is secured in place by the screwing downof the cap upon the diaphragm and the gasket ring.

Within the tube 6 and the nozzle 5 is located a stem 9, which is securedat its upper extremity to the diaphragm 7 by means of washers 10 and 11,and a nut 12 which screws on to the threaded extremity of the stem.Formed integrally with the stem, near the upper portion thereof, areguide blades 13 at right angles to each other, which keep the stemalined centrally within the tube, but freely permit the flow of waterthrough the tube. The nozzle 5 has an opening in which a lever 14 ispivoted on a pin 15. The extremity of the lever 14 projects into thenozzle 5 and engages with the lower portion of thevstem 9. The pin 15 isheld in place by means of a threaded member 20. The other end of thelever is-provided with a button 16, by means of which it may beconveniently depressed in operating the faucet.

The diaphragm 7 is provided with a rivet 17, in which is an opening 18which permits the water to flow through the diaphragm into the recess 19of the cap and thus to press upon the diaphragm and force the sameagainst the opening of the tubular body 6. It will be understood thatthe area of the diaphragm against which the water pressure is exerted onthe upper side, is greater than the corresponding area on the under sideof the diaphragm; and consequently, the unbalanced pressure will besuicient to depress the diaphragm against the opening.

When it is desired to open the faucet, the lever 14 is presseddownwardly: this raises the stem 9 and diaphragm 7 the water above thediaphragm and in the recess iiowing out through the opening 18. Thewater then flows through the pipe into the chamber 2 and through thetube 6 between the guide blades 13 and then out through the nozzle 5. Toshut off the flow of water, it is merely necessary to release the lever,when the ressure of the water upon the upper side of) the diaphragm issufficient to force the latter against the tube 6 and thus close thesame.

In case the water pressure is found insuicient to operate the closing ofthe faucet, an

auxiliary spring can be inserted between the cap 3 and nut l2 to assistin forcing the dia-Y phragm downwardly when the lever is released.

It will be understood that the diaphragm 7, being located between theupper rim of the chamber and the cap, may act as a gasket or packing andif desired, it is possible to dispense with the extra packing ring S. Iffound desirable in practice, a washer lmade of hard rubber may be placedbetween the washer 11 and the diaphragm 7, thereby prolonging the lifeof the diaphragm when the device is used in connection with a hot Watersupply.

Having thus described my invention I claim as new and desire to secureby Letters i Patent:

1. A faucet, comprising a chamber having ed within said chamber andadapted to close the inner extremity of said outlet, said diaphragmbeing formed to permit the fluid to pass to the upper side thereofwhereby the pressure of the fiuid forces the diaphragm v into a positionagainst said outlet, a stem sei cured to said diaphragm and guidedwithin said outlet, and means for manually operating and controllingsaid stem to raise said diaphragm.

2. A faucet comprising a chamber having a tubular outlet projectinginwardly and outwardly, a flexible diaphragm mounted within said chamberand adapted to close the inner extremity of said outlet, said diaphragmbeing formed to permit a fluid to pass to the upper side thereof,whereby the pressure of the fluid forces the diaphragm into a positionagainst said outlet, a stem secured to said diaphragm and having lateralguides within said outlet, and a lever adapted to be manually operatedand controlling said stem to raise said diaphragm.

3. A faucet presenting a chamber, a cap having an inner recess, atubular outlet, a flexible diaphragm secured within said chamber andsaid cap and arranged to close said outlet, said diaphragm being formedto admit a fluid to said recess, wherebythe fluid pressure normallyholds said diaphragm against said outlet, a stem in said outlet havingguides secured to said diaphragm, and a lever pivotally lmounted at aside of said outlet, said lever being adapted to be manually operated toraise said stem.

4. A faucet comprising a chamber, an outlet, a tube within said chamberin communication therewith and with said outlet, a cap having a recess,a flexible diaphragm mounted over said recess and adapted to close saidtube, said `diaphragm having an opening therethrough to permit theentrance of Aa fluid to said recess, whereby the fluid pressure normallyholds said diaphragm against said tube, a stem secured to said diaphragmand having guide blades within said tube, and a lever pivotally mountedat a side of said outlet and adapted to be manually depressed to raisesaid stem.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

PATRICK F. CAVANAUGH.
